According　to　the　International　Technology　Roadmap　for　Semiconductors　(ITRS),　improving　characteristics　of　metal　wires　will　no　longer　satisfy　performance　requirements　for　future　large　scale　MPSoC　systems,　and　new　interconnect　paradigms　are　needed.　Different　revolutionary　approaches　like　optical　interconnect,　Radio　Frequency　Interconnect　(or　RF-I),　wireless　interconnects　with　CMOS　ultra　wide　band　(UWB)　technology　have　been　explored.　The　hybrid　hierarchical　architecture　with　Wireless/RF-I　backbones　is　more　cost-efficiency　and　feasible　due　to　the　advantages　in　CMOS　compatibility　compared　with　other　alternative　interconnects,　and　has　become　one　of　the　mainstreams　of　CMP　architectures.　However,　how　to　design　an　efficient　HNoCs　is　a　new　challenge.　This　work　provides　the　architecture　design　flow　of　the　HNoCs　with　wireless/RF-I,　and　explores　the　key　problems　in　the　architecture　design　from　the　perspectives　of　topology,　resource　management　strategy　and　routing　problems,　which　are　different　with　traditional　metallic　interconnections.　©　2013　IEEE.
